CYLINDER WASHING-I-IVIACHINEQ SPECIFICATION forming part of LettersPatent No. 335,710. dated February 9, 188 6.

Application filed June 1, 1885.

' machines, and has for its object to improve the construction andoperation of the same.

In the drawings, Figure 1 is a vertical longitudinal section; Fig. 2, asection on the line as x of Fig. 1; Fig. 3, an end view of the cylinder;and Figs. 4 to 9, inclusive, views illustrating certain detailshereinafter more fully set forth.

This invention is designed as an improvement upon that for which LettersPatent of the United States were granted to me, hearing date March 6,1883, and numbered 27 3,584.

A A indicate the heads or ends of the machine, B B the sides, 0 thebottom, and D the cover.

The heads A, sides B, and top or cover D are made of wood, and thebottom 0, which is curved, is made of zinc, galvanized sheet-iron, orlike thin metal.

In order that the bottom 0 may be firmly secured in place and awater-tight joint be secured, I adopt the construction shown in Fig. 8.

The sides B are formed with vertical grooves a, into which the heads areseated; and they are also formed with grooves b in their lower edges,which grooves extend from the vertical groove a at one end to thecorresponding groove at the other end. In these grooves b are insertedthe edges of the curved zincbottom O as clearly indicated in Fig. 8.

The heads A, when in place in the grooves a, tend to retain the curvedbottom in place, as the latter extends across the full width of thegroove a, as shown in Fig. 8.

It will be seen that I am enabled to produce a strong and water-tightjoint between the parts A B O, and that I am enabledto dis pense withnails or screws along the lower edge of the sides, though rivets orlight nails may be used, if deemed desirable.

The tub or body thus constructed is supported, upon legs 0, or in anyother suitable manner.

E indicatesthe cylinder, consisting of heads d d and longitudinalV-shaped bars or rods e, connecting the heads, said cylinder E beingcarried by a shaft, f, mounted in bearings g g, secured to the heads orends of the tub, as shown in Fig. 1.

As shown more clearly in Fig. 2, the heads (I are provided with a seriesof V-shaped notches or recesses, h, in which the correspondinglyV-shaped bars e are seated, the notches it being of such a distanceapart as not to allow the bars e to touch one another. This is to allowthe water to enter and leave the cylinder readily.

As shown in Figs. 1 and 2, the notches h are cut away entirely acrossthe narrow edge or periphery of the heads d, so as to allow the ends ofthe bars e to come flush with the outer face of the heads. Thisconstruction is advantageous in that it forms a hearing or seat ofconsiderable width for the bars e, and strengthens the cylinder to agreat extent.

In order to retain the bars 6 in place, I provide a metallic band, t,preferably zinc, which extends over the ends of the bars 6, as shown inFigs. 1, 2, and 3, and through each. of the bars 6 and the band 2', Ipass a nail or a screw, iwhich extends preferably into the head andsecures the parts firmly together.

In order to allow the clothes to be placed in the cylinder E, I providethe latter with a hinged section or door, j, (shown in Figs. 2, 3, and5,) said section forming about onefifth of the circumference of thecylinder. The doorj is carried at each end by a hinge,- k, secured tothe heads and to the door, as

clearly shown in Fig. 3, and to keep said door or hinged section closedI provide the latter with a pin or stud, Z, which enters a hole, m, inthe hinged catch n, secured to the heads (I.

In order to prevent the movable leai of the hinged catch a fromfallingtoo far back, I provide a staple or guard, 2, against which the upperpart of the catch rests when the sectionj is opened.

The ends of the, hinged door j are encircled by a metallic band, 'i, inthe same manner as the ends of the main body of the cylinder.

Both faces of the parting line of the door j and cylinder E will, uponreference to Figs. 2, 3, and 5, be seen to be covered and protected bythe band The shaft f, upon which the cylinder E turns, is provided withcylindrical ends, which are carried'in the bracketso'r bearings 9, saidbrackets'or bearings'being slotted vertically, as shown in Fig. 1, toallow the cylinder to be lifted. bodily out of the tub.

Securely fastened to the shaft f is an inner roll or bar, F. This rollor'bar maybe'sa cured upon the shaft f by means of screws, or theshaftmay be squared, as indicated in Fig. 4, in which case I prefer tomake the "roll F in two parts and to fasten them together by screws.This prevents the shaft f turning independently of the roll. The roll Fis polygonal in cross-section, and is provided with blades are concavedepressions p; extending lengthwise of the cylinder. YVhen the clothesare lifted-by the larger cylinderE, theyfall upon the edges of the ribsor blades o of roll F and cause the latter to turn in'an oppositedirection from cylinder'E. The cylindrical ends of the roll F fit andrevolve within rings q, secured concentrically about the shaft f on theheads "d, as shown in Figs. 1 and 2, said rings q preventing clothes andother "articles from getting in around the ends of the roll F, and beingtorn thereby.

In order to support and give strength to the heads (1, I provide eachwith'a plate, 1', preferably of castmetal, said plates covering a largeportion of the heads, and provided with arms 8, as shown in Fig. 3.These'plates r are secured in place by screws or inanyother suitablemanner. As shown in Figs. 1, 3, and 7, one of the plates r is providedwith agear-wheehit, which meshes with a pinion, u, carried-by'a shaft,1). The shaft 1) is provided with a'crank orhan'dl'e, w, and revolves ina tubular sleeve or bO Xst, in the head A, as clearly indicated in Fig;7, the shaft '1) being of a lengthgrea't'er than the length of thesleeve 00, in order thats'aid shaft 12 and its pinion u may havealon'gitudinal movement.

When it is desired to impart motion to the cylinder E, 'the'shaft o ismoved inward'until its pinion u meshes 'with'the gear "15 on thecylinder, and in order to keep said gears in 'mesh I provide a pivotaldog, y, whichdrops down between the pinion wand head Aand prevents endmovement of the shaft.

When it is desired to remove the cylinder E from the machine, the dog yis thrown upward, as indicated in Fig. 6, and the shaft 1) is slidlongitudinally outward, thereby moving its pinion u out of mesh with thegearwhcel t, as indicated in Fig. 1, and by dotted 7 lines in Fig. 7.The cylinder E can then be lifted bodily 'out of'the tub, the bearing 9being slotted vertically for this purpose, as .above mentioned.

It will be seen that the only opening through the heads A of the machineis above the waterline,"and thus leakage is obviated.

In order to insure the positive movements of the cylinder E and the rollF in opposite directions, I adopt'the construction shown in Fig. 1, andmore clearly in Fig. 9.

G indicates a stationary plate secured to one of the'heads A,provided onits periphery with gear-teeth, said plate being preferably provided withthe slotted bearing 9 for the shaft f.

The bearing 9 may be made separate and independent fromthe plate'G, ifdesired, but I prefer to cast them all in one piece, as it givesstrength'to the'heads A.

' Attached to and moving with the cylinder E 'is'a' shaft, H, carryingthe double gear wheels I J ,the former to mesh with the gearplateG'andthe other to mesh'with the gear K, firmly keyed or otherwise secured tothe shaft f, as show nin Fig.9." 'As'the cylinder is rotatcd the shaft'H, carried thereby, travels around" with it, the gear-wheel I receivingmotion from the stationary gear-ring G, the motion thus secured beingtransmitted by gear J to the gear'K on-shaftf.

' The direction the gears take is indicated by arrows in Fig. 9, and itwill be seen upon reference to said figure that cylinder E and gears I Jhave a direction contrary to that of gear K.

Having thus described my invention,what I claim is-- 1. In a cylinderwashing-machine, the combination of a tub or receptacle, a cylinder, ashaft therefor, slotted bearingsfor said'shaft, a gear-wheel mountedupon the cylinder, and apinion meshing with said gear'and movablelongitudinally out of mesh with the gear, as
